ROLLER-PRESS.

Specification of Letters Patent.

Application filed October 30, 1906. Serial Non 341.284.

Patented Feb. 25, 1908.

To all whom 'it may concern:

Be it known that 1, CHnrsTEN NEILSEN, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Roller-Press, of which the following is a specification.

This invention relates to apparatus for eX- tracting oil from castor beans, linseed, cotton seed, and the like, and has for its principal object to provide a powerful press of compact construction which will act on meal in comparatively small quantities in order to insure thorough separation of the oil therefrom.

A further object of the invention is to provide a roller .press in which relatively small rolls may be used, the necessary pressure being obtained by forcing the rollers together by the employment of hydraulic jacks or similar iiuid pressure apparatus.

A still further object of the invention is to provide a press of this type in which the meal is carried through the press by a pair of endless belts or aprons formed of suitable material through which the oil may be strained or ltered while the meal is carried on through the press and discharged at the opposite side.

With these and other objects 1n view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

1n the accompanying drawings z-Figure l is a sectional elevation of an oil press constructed in accordance with the invention.

Fig. 2 is a front elevation of the same.

during the operation. Guided in the upper portions of the slotted cheek plates are bearing blocks 18 carrying a shaft 19 on which is secured a roller 20, of a length about equal to the distance between the two flanges ofthe lower roll. The bearing blocks 18 of the upper roll are forced downward by means of hydraulic jacks 21 that are disposed between the bearing blocks and the caps 12, and are connected by pipes 23 to an accumulator or other source of fluid pressure supply, this construction and arrangement permitting4 the use of relatively small and light rollers.

The base is provided with bearings 30 for the reception of a shaft 31 which carries a belt wheel 32 and a pinion 33. This pinion intermeshes with a gear 34 mounted on a shaft 35 that is supported on bearing brael ets 36 projecting from the cheek plate. At that end of the shaft opposite the gear 34 is a pinion 37 which intermeshes with a gear wheel 38 on the shaft of the lowermost roll, and at the opposite end of the roller shaft is a gear 3Q which intermeshes with a twin gear 40 on the shaft of the upper roll,

Formed on or projecting from the cheek plates or standards are arms carrying suitable bearings for the support of four upper shafts 43 and four lower shafts 44, each of these shafts carrying a small guiding roller. The rollers of the upper set of shafts carry an endless belt or apron 47, and the rollers of the lower set of shafts carry an endless belt or apron 48, the two aprons being formed of any suitable material through which the oil may be filtered or strained, such, for instance, as camels hair cloth. The upper run of the lower belt is arranged approximately hori- Zontal, while the lower run of the upper belt is somewhat inclined, thereby forming at the entrance side of the press a receiving surface on which the meal may be deposited from a seed spout 50. Y

Secured between the cheek plates at a point below the lowerroller is an oil receiving pan 51, the pan being disposed at a point above the lower run of the lowermost belt, and all of the oil which'enters this pan must first filter or strain through the lower belt.

In the operation of the press, the meal or other material is placed on a receiving platform formed by the upper run of the lower belt, and is carried between the two belts and rolls. The pressure is such that the larger percentage of the oil will not pass between the rollers, but will `bedriven through the lower belt at the entrance side of the point of contact of the rolls, the oil runnin downover -thesurface of the roll to the oi pan, and being guided thereto by the end ilanges of the lower roll. These end4 flanges are also of importance in that they prevent vthe escape of theo'ilflaterally-of the press,l so lthat no o'il can'low down over the en'dsof the lowerroll.

As the surface speeds -of` theI two rolls are the same and the Abelt ory aprons are driven lby the rolls, there vis no sliding fric-tion on the bel-ts, and they-'will last for a comparatively long period of time. As the material` is treated Iin rela-tively small quantitieathe mlaterial dischargedwill be dry and free from o1 Aroller press comprising a suitable base, a `pair of opposed cheek plates or standards having vertical slots, a roll having journal supports in the loweryends of said slots and provided with end flanges, another roll vdirectly above the first-named roll and having journal bearings adjustably mounted in said slots, cap plates closing the upper ends of the slots, hydraulic acks interposed between the cap plates and the journal bear ings of the upper roll, a pair of endless belts, one for each roll, carrying rollersy for the bel ts,vjournal supports for the belt rollers projecting from said cheeks 0r standards, and a receiving pan located above' the vpath of' the lowermost runy of the belt i assing around the lower roll and. entered y said lower roll and the iianges thereof.

In vtestimony that I claim the foregoing as my own, I yhave hereto affixed my signature in the presence of two witnesses.
